Early Reduction of Pulmonary Artery Pressures Is Associated With Improved Mortality Among Medicare Beneficiaries With Heart Failure
Main finding · 2-year mortality by baseline PAD (cohort A)Result — go to the resultHazard ratio 0.68 95% CI 0.62–0.73Authors' conclusion
Among Medicare beneficiaries, CardioMEMS-guided management was associated with a reduction in PAD. Achieving acceptable PAD within 90 days of implant was associated with better survival.
Study context

- 9,579 beneficiaries
- Exposure
- Acceptable vs elevated PAD (baseline); improved vs persistently elevated PAD at 90 days
- Outcome
- Mortality
- Follow-up

| Outcome | Improved PAD | Persistently elevated PAD | HR (95% CI) | P value | |
|---|---|---|---|---|---|
| Mortality by 90-day PAD trajectory (cohort B) · mortality | 24.0% | 76.0% | 0.72 (0.64–0.81) | P < 0.001 | |
| ΔPAD | −6.5 ± 4.3 mm Hg | −1.6 ± 4.3 mm Hg | |||
| 0.512Hazard ratio (log scale) |
- Mortality by 90-day PAD trajectory (cohort B): 63.3% elevated at baseline in cohort B; percentages are of those
Predictors of improved PAD
- Lower baseline PAD and no history of COPD or atrial arrhythmia associated with higher odds of improved PAD
